Cooperative ITS Credentials Management System
Overview
The 'Cooperative ITS Credentials Management System' (CCMS) is a high-level aggregate representation of the interconnected systems that enable trusted communications between mobile devices and other mobile devices, roadside devices, and centers and protect data they handle from unauthorized access. Representing the different interconnected systems that make up a Public Key Infrastructure (PKI), this physical object represents an end user view of the credentials management system with focus on the exchanges between the CCMS and user devices that support the secure distribution, use, and revocation of trust credentials.
As the CCMS interacts with mobile devices and other devices in the Connected Vehicle (CV) environment, these devices pass through stages as certificates and cryptographic material are furnished that enable the device to have trusted interactions with other devices in the CV environment. A simplified version of the device security life cycle is depicted in the following figure.
Unprovisioned: The device does not have any of the crypto material or certificates necessary to interact with any parts of the CCMS other than the Provisioning components. Since the end entity is not part of the C-ITS at this stage, it cannot interact in trustworthy fashion with other end entities.
Provisioned and Unenrolled: The device has the crypto material and root certificates necessary to communicate with Enrollment components. At this stage the end entity is still not part of the C-ITS and cannot in trustworthy fashion interact with other end entities.
Enrolled and Unauthorized: The device has all the material it needs to communicate with Authorization components. It still cannot interact with other end entities in trustworthy fashion.
Operational: The device has all the material it needs to communicate with the Misbehavior components, Revocation components, and other operational end entities.
End-of-Life: The device is unable to communicate with any component of the CCMS or other end entities.
